I called the local Dodge dealer today,looking for 4.875 gears.
I had them look it up for a 87 Dodge Raider. I was told they only listed 4.625, and they were not available.

What I have read here on the wire ,is that they came in High altitude models. High Altitude models of what? Are they available for the 2.6? Has anyone ever seen a high altitude model?

PowerRam50 you found a set, What were they in?

I really need to find a set of these gears, As I can not get 4.625 for the front of my truck.(Dana 30) But I can get 4.88

Well on my way to becoming that eccentric old man in every town.(crazy as a s#@thouse rat) With a yard full of desireable old vehicles that tells you, Sorry they're not for sale..... Someday I'm going to fix them.
